Abstract
There is provided a flameholder 370 for a reheat assembly 300, 300A of a gas turbine engine 10. The flameholder comprises an internal flow passageway 376 extending from an inlet aperture 374 and defining a flow direction F for flow through the flameholder 370. The internal flow passageway 376 is defined by an internal surface 34 of the flameholder 370. A grid of recesses 31 is formed in the internal surface 34 of the flameholder 370.
Claims15
A flameholder for a reheat assembly of a gas turbine engine, the flameholder comprising:
- an internal flow passageway extending from an inlet aperture and defining a flow direction for flow through the flameholder, the internal flow passageway defined by an internal surface of the flameholder;
- and
- a grid of quadrilateral recesses formed in the internal surface, the grid being oriented so that diagonal directions of the recesses correspond to the flow direction.
A flameholder for a reheat assembly of a gas turbine engine, the flameholder being in the form of a unibody, wherein the flameholder comprises:
- an internal flow passageway defined by the unibody and extending from an inlet aperture to an outlet aperture and defining a flow direction for flow through the flameholder, the internal flow passageway defined by an internal surface of the flameholder;
- and
- a grid of recesses formed in the internal surface, the grid having a continuous extent along the flow direction, the continuous extent being at least 25 percent of a length of the internal flow passageway.
